CTB-002 Reference Optical Response
CTB-002 is a cooling color-correction filter referenced to the customer sample book. Evaluate the correction with the spectrum of your actual light source.
Optical performance
- Measured wavelength range: 380-780 nm. Performance outside this interval is not established.
- Peak transmission: Approximately 86.040% at 435 nm. This is a sample measurement, not an order tolerance.
- Selection note: The customer sample-book curve is the reference for this listing. Confirm that your sample-book edition and order refer to the same design.
These values describe a measured measured sample. Custom versions and production orders have their own agreed specifications.

Questions about CTB-002
Why does this CTB-002 listing use the sample-book curve?
This listing follows the customer sample-book reference over 380-780 nm. Its measured peak is 86.040% at 435 nm. If your factory sheet looks different, send us the edition or label rather than assuming the curves describe the same version.
Can I choose CTB-002 from its peak transmission alone?
The sample peak of 86.040% at 435 nm is only one point on the curve. Compare the complete sample-book spectrum with your actual lamp: the balance of blue, green and red light determines the correction. Share your source spectrum and target color balance with us.
